Answer:

Step-by-step explanation:
( x + 3 )( x - 8 ) =
- 8x + 3x - 24 =
- 5x -24
X = 180 - (90 + 47)
x = 180 - 137
x = 43
answer angle x = 43
Answer:
33%
Step-by-step explanation:
Since you know the given angle is 46deg. You also know that a straight line is equal to 180deg. So it's a supplementary angle, therefore you subtract 46 from 180 and get 134. And since the l, m, and n are parallel, they have congruent angles. So x = 134deg.
